Review of Smoothie: Now that’s the stuff! Hands down the BEST smoothie of the bunch. Next time, try with 1 banana as it’s too sweet. Makes 2 1/2 Glass-fulls. After doing this for 7 days, I’ve noticed that my body only really wants around 1 1/2 Glass-fulls. Maybe I’m drinking too fast or maybe I should just drink 1 1/2 Glass-fulls?
